How to Survive the Freezing Cold

The two main cold weather conditions are frostbite and hypothermia. Frostbite means your skin is already freezing, and ice crystals are formed in your skin cells and kill them. If you can warm your skin, it forms a blister, the color changes from blue to black, and it solidifies in the shell. If the damage is not so serious, the shell will eventually fall and a new skin will appear below. This is a very painful "surface" frostbite. Severe frostbite has penetrated muscle and bone and is characterized by tingling pain in the limbs and changes in color and texture of the skin. The stage of frostbite is as follows.

Severe frostbite usually causes tissue damage and may even cause fingers, toes, hands, even feet cutting. When there is frostbite, it is important to gradually warm your skin. Cover your ears and place your fingers under the arms. Do not damage damaged skin or soak it in hot water. It gets scratched. Water between 100 degrees Fahrenheit and 106 degrees Fahrenheit is ideal for use as a global warming agent. If possible, even if it is just a tent or a shelter, please enter a warm place immediately. Remove all clothing that may restrict blood flow. You can add gauze or cloth between your fingers and toe to absorb moisture and prevent them from sticking together. It will also help to increase the affected area slightly to reduce swelling

Hypothermia means that your body loses more heat than you produce and your central body temperature falls. Some symptoms of hypothermia are as follows.

In many cases, when wet for non-cold reasons, hypothermia may occur, which may be as serious as coma or death. Please enter a warm environment as soon as possible so as not to lower the antibody temperature too much. We cover everything we can find, such as blankets, sleeping bags, pillows, and even newspapers. Most heat is lost through your head so if you do not have it yet, cover your heat soon. If you are wearing wet clothes, remove it and replace it with a dry dam. If you do not have clothes, it is advisable to take off your clothes rather than wear wet clothes. Please beware that victims of hypothermia are liable to be arrested by the heart. Flatten and calm them - to ensure they will be better. If you are with someone, you can put a sleeping bag together or hug you together to create warmth. If you are not trapped in the wilderness, please receive specialized treatment as soon as possible.

Deciduous trees need some degree of protection against freezing temperatures and other harsh winter. Stems, branches and sprouts can survive even in extreme cold environments. Since young leaves freeze in the winter, these plants must handle them. Corresponding to the shortened number of days and the decrease in sunlight intensity, the leaves begin to decay them. As a layer of cells is formed at the base of each leaf, the veins carrying the fluid entering and leaving the leaves gradually close. These blocked veins will capture the sugar in the leaves and promote the production of anthocyanins. Once the separation layer is completed and the connective tissue is sealed

Several Holarctic amphibians and reptiles survive the coldness of winter by enduring the freezing of their body tissues. Several mechanisms for adapting to freezing adaptation in vertebrate in vitro adaptation are known, but little is known about the factors driving the evolution of this trait. Efforts to do so may contribute to concentration in amphibians, which often shows strong clinical changes in cold resistance (Brattstrom, 1968; Snyder and Weathers, 1975). Rana sylvatica (LeConte 1825) is a very useful species in these studies due to its wide geographic extent and extends to 69 ° N in the Arctic Circle (Martof and Humphries, 1959).

Hibernation physiology of frog in the northern frog, freezing adaptation and extreme frost resistance

Frogs usually reach body temperature compatible with the surrounding environment. This function seems to prevent the influence of cold caused by fatal freezing in winter, but many species live in mid latitude because many species can live in hibernating state without frost (eg under the pond) . In addition, recent research shows that at least five species are from North America - Hailea Chrysoselis (Schmid 1986, Costanzo et al 1992b), Hira versicolor (Schmid 1982), Pseudacris crucifer (Schmidt 1982) , Pseudacris tl-iserjata (Storey & Storey 1987) Sylvatica (Schmid 1982) - Winter body fluids are frozen to temperatures as low as -8 ° C. This unique adaptability allows these species to hibernate under the surface of the forestry waste as it is inevitable to be exposed to temperatures below freezing.
